DYNAMIC RADAR CRUISE CONTROL SYSTEM > Distance Control ECU Power Source Circuit

for Preparation Click here


DESCRIPTION

This circuit provides power to operate the distance control ECU (cruise control ECU). The distance control ECU determines information about the vehicle in front based on data from the radar sensor, and then decides how much acceleration and / or deceleration is needed to maintain the set distance. The distance control ECU also requests the skid control ECU to apply the brakes and sound the buzzer.
